Feature: Mocking with `rspec`

  RSpec uses its own mocking framework by default. You can also configure it
  explicitly if you wish.

  Scenario: Passing message expectation
    Given a file named "example_spec.rb" with:
      """ruby
      RSpec.configure do |config|
        config.mock_with :rspec
      end

      RSpec.describe "mocking with RSpec" do
        it "passes when it should" do
          receiver = double('receiver')
          expect(receiver).to receive(:message)
          receiver.message
        end
      end
      """
    When I run `rspec example_spec.rb`
    Then the examples should all pass

  Scenario: Failing message expectation
    Given a file named "example_spec.rb" with:
      """ruby
      RSpec.configure do |config|
        config.mock_with :rspec
      end

      RSpec.describe "mocking with RSpec" do
        it "fails when it should" do
          receiver = double('receiver')
          expect(receiver).to receive(:message)
        end
      end
      """
    When I run `rspec example_spec.rb`
    Then the output should contain "1 example, 1 failure"

  Scenario: Failing message expectation in pending example (remains pending)
    Given a file named "example_spec.rb" with:
      """ruby
      RSpec.configure do |config|
        config.mock_with :rspec
      end

      RSpec.describe "failed message expectation in a pending example" do
        it "is listed as pending" do
          pending
          receiver = double('receiver')
          expect(receiver).to receive(:message)
        end
      end
      """
    When I run `rspec example_spec.rb`
    Then the output should contain "1 example, 0 failures, 1 pending"
    And the exit status should be 0

  Scenario: Passing message expectation in pending example (fails)
    Given a file named "example_spec.rb" with:
      """ruby
      RSpec.configure do |config|
        config.mock_with :rspec
      end

      RSpec.describe "passing message expectation in a pending example" do
        it "fails with FIXED" do
          pending
          receiver = double('receiver')
          expect(receiver).to receive(:message)
          receiver.message
        end
      end
      """
    When I run `rspec example_spec.rb`
    Then the output should contain "FIXED"
    Then the output should contain "1 example, 1 failure"
    And the exit status should be 1

  Scenario: Accessing `RSpec.configuration.mock_framework.framework_name`
    Given a file named "example_spec.rb" with:
      """ruby
      RSpec.configure do |config|
        config.mock_with :rspec
      end

      RSpec.describe "RSpec.configuration.mock_framework.framework_name" do
        it "returns :rspec" do
          expect(RSpec.configuration.mock_framework.framework_name).to eq(:rspec)
        end
      end
      """
    When I run `rspec example_spec.rb`
    Then the examples should all pass

  Scenario: Doubles may be used in generated descriptions
    Given a file named "example_spec.rb" with:
      """ruby
      RSpec.configure do |config|
        config.mock_with :rspec
      end

      RSpec.describe "Testing" do
        # Examples with no descriptions will default to RSpec-generated descriptions
        it do
          foo = double("Test")
          expect(foo).to be foo
        end
      end
      """
    When I run `rspec example_spec.rb`
    Then the examples should all pass
